Room Temperature Crosslinking Acrylic Ester Emulsion Synthesis Performance Study Of Its Use As The Application Of Leather Finishing Agents

An ambient Crosslinkable acrylic polymer emulsion was obtained by adding adipic acid dihydrazide to the acrylic polymer emulsion incorporated with diacetone acrylamide(DAAM). Study shows that the cross-link reaction occurs in the later drying stage of the emulsion when the ammonia volatile and the pH volume of the drying film become low. Study also shows that the cross-linked film of the emulsion has better water and solvent resistance and the scope between brittle point and stick temperature are greatly widened. The main points of this dissertation consist of the following points:1 . yrene/acrylic emulsion proked in detail the prospects and present condition of itsapplication.2 . Using DAAM as a functional monomer and hydrazine as crosslinkingagent,according to the theory of emulsion influence of different polymeric conditions,we synthesized the crosslinkable acrylic polymer emulsion.3 . By the Dsc,we studied the crosslinking reaction and film properties.4. Study on Ambient Crosslinkable Styrene Acrylic Emulsion for applications in leather finishing agent. Compared with non-crosslinkable acrylic polymer emulsion,the title emulsion had much more improved film properties., the comprehensive performance of the leather finishing agent is good the other factors are discussed.
